| Abstract: | Based on the characteristics of tool-style tubular steel formwork-supports,the authors analyze the theoretical calculation of bearing capacity with single tube,including the calculation of allowable bearing capacity for tool-style steel tube,and the comparison with 48mm×3.5mm steel tube pole;the authors introduce bearing capacity test of single tool-style steel tube,and discuss bearing capacity test for multi pole assembly,including the determination of test scheme for formwork-supports,the test results are analyzed and summarized.Facts show that tool-style tubular steel formwork-supports system whose force is reasonable is safe,the work efficiency is improved. |
